RE: ONE RECEIVER OR TWO??
Guys.. the whole dual receiver thing started because we got worried the receivers couldn't handle the current draw created by the ever growing aircraft and hence servo requirements. This turned out to be unnecessary. While I can't speak for Futaba.. I do know the JR 955S is capable of handling a burst of nearly 60 amps.
I only run 1 receiver anymore. I don't feel 2 is necessary.
